Be it known that I, E IT .G. LA r'rma citizen of the" United St ates,- r esiding at Friend- I ship, in thecounty of Allegany and State of New York, have" invented ,new and useful Improvements "in Ribbon Mechanisms for achines, of which the follow cation, r This invention relates to ribbon mechanisms. for frontwstrike or visible writing typewriting machines, was more particularly designed for fron't strikeniachlnes of the character disclosed a plieation for patents, Serial No.'168,190, fled Auguste, 1908; Serial No. 169,134, filed August '11, 1903, and Serial No. l79,lil 9, fil'ed October The object or the meta-its is to rovide an improved ribbonj operatingimec ianism whereby the ribbon is cansedto feedlengthwise from one spool to the other'and to. move laterally or crosswise in frontoffthe' printingpoint of the platenbymeans'inde endent of the type bar action or the universa bar, so as the operator.

operative to relieve these parts of the work'of operating the ribbon and insurea light easy touch} and having a ribbon guide orjvibrator which may' be set to move the ribbon to expose the print ing-point after each impression or only upon the actuation of th space-keyat" the of Another object of the invention is to protvide a vibrating'index to show the location of the rintingointand'also'constitnting a scale w 'ch. can e readily turned backout of position and, out of the way when not required.

In the accompanying drawings, consisting of three sheets, Figure 1 is a longitudinal sec: tional elevation of parts of a typo-writing ma chine provided with a ribbon mechanism embodying the invention. Fig. 2 is a transverse sectional elevation thereof, showing the can, riage by broken lines. Fig. 3 isa plan View thereof, partly in horizontal section.

The spools may be of any suitable construction and are the position of the feed device reversed. Fig;

The spools are both rotatably mounted on a spool support or carrier, which has a vertical pivotal connection at its front end with the.

upright standard a, at the frontgpart of the main frame, so that its rear end can swing laterally back and forth in front of the platen. 1

The spool support or carrier is preferably constructed as shown in the drawings, consisting of a substantially rectangular frame movably engage and bear in vertical holes in studs out'of their bearing-holes.

horizontal portions 71 it of the upright standard a. The speel support can'be readily'removed from the machine by lifting its pivot- The ribbon passes between the spools through a suitable uide and vibrating device,to be hereinafter escribed, which holds the ribbon in a substantially vertical position in front of the printing-point in the path of the type. -When the rear end of the spool support or carrier is swung laterally, the vertical port on ofthe ribbon is moved laterally or transversely back and forth in front of the printing-point,

so that the entire available width of the ribbon is used, and the wear thereon is uniform throughout its width. The'spool support or carrieris swung on its,

vertical pivot to thus carry the ribbon l'ater.

ally acr ss the printing-point of the platen by the fol owing mechanism: K represents a scroll or volute shaped cam which is secured 'to or formed on the-front sideofthe-powerdriven drum or barrelC, which operates the carriage. One arm of the bearing for the rear ribbon-spool, preferably the right-hand arm, is provided with a rearwardly-project-' ing finger or portion 7c, which is he against the peripheral face of the cam K by a suitable sprin preferably "acurved leaf or fiat spring k, B ig 4, secured to the upright standard a and bearin at its free end against the right-hand side of the frontbar or portion of thes'pool-support. When theoperator shifts the carriagezto the right to commence a new line, the cam,'acting againstthe finger on the spo0lsup ort, moves the rear end of the latter tower the right with the carriage, and as the carriage is moved step by step or inter-r erabiy v U-shaped leVerM, pivoted at min any suitmittently toward the left in the operation of the machine by the power-driven drum the finger on the spool-support is held against the-periphery of the cam K and is thus permitted to move gradually or slowly toward the left. The proportion of the parts is such that the ribbon is moved crosswise a distance equal to its available width at each complete movement of the carriage. The lateral movement of the ribbon toward the right is thus effected by'the operator in moving the carriage tothe right, and the ribbon is moved to the left by the spring is, so that the typebar action is not only relieved entirely of this work, but the carriage-driving spring is also free from it, therefore permitting the use of a lighter carriage-driving spring and reducing thenoise and wear of the carriage-escapement. l

The spools are rotated to feed the ribbon longitudinally by mechanism preferably cohstructedas follows: L represents a feed bar or device which is of substantially U shape and is slidably secured to one of the side bars of the openframe of the spool-support in any suitable 1nannerfor instance, by rivets or pins Z-p'assing through elongated slots Z in the bar. The iront and rear arms of the feedbar extendinwardly or toward the ribbonspools, the front arm projecting beneath the adjacent ratchet-wheel of the front spool, while the rear'arrn extends over the adjacent ratchet-Wheel of the rear spool. The front arm .of the feed-bar is provided with an upwardly-projecting edge or portion Z consti-' tutin a pawl to engage the teeth of the wheel of the front s 001 and the rear arm of the feed-bar is provided with a downwardlyex-tending portion 1 to engage the teeth of the ratchet-wheel of the rear spool. The feed-bar is made of spring-metal, and its arms are pressed yieldingly toward the spools to enga e the teeth of their respective ratchetwhee s. of the feed-bar are inclined cream-shaped at Z Z", respectively,"Figsl 5-10.
